There are a number of threads that discuss the best Words of Power spells (this one, for instance), but I haven't noticed any threads discussing which words to stay away from.
Here's a few duds that I've found. Prove me wrong!
Special mention goes to the Barrier target word: it allows you to make a wall that's 10' or 20' long per level, but you're still limited to Close range which really restricts the area you can affect.
(Note: I actually like the Words of Power system, so please don't think I'm just being negative!)

I look at it this way. Words of power are a more primordial magic. There is a reason that spellcasting became wizardry and such, it is a refinement of magic to achieve different and in many cases, greater affects.
Some of the words had to be less effective to keep this concept realistic or else magic never would have changed into spellcasting (and the assumed greater effects it brings).
Does that make sense?

@Gilfalas that makes sense thematically, but that doesn't mean that those words are any good. While flavor is good, I'd prefer that when paizo introduces a system like this (and don't get me wrong, I love this system) that they make it so there isn't anything that is ENTIRELY useless. That's just my 2 cp though.

You know what? I'm an idiot. The Rumble word I mention with a small Burst area can indeed have its area boosted. For whatever reason, I'm always mixing up "Boosting this effect word increases its level by 2" (what it actually says) with "Boosting this effect word increases the wordspell's level by 2" (how I'm reading it).
So, in fact, you can have a biggish Rumble spell. D'oh!

Personally, I find it easier to imagine that making Dimensional Shift affect only the caster (for instance) was more of an oversight than an intentional flavour change (since the main difference between Dimensional Shift and Plane Shift was subtle enough that I didn't notice it at first), but who can say?
